- Advanced Digital I/O (ADIO) module for APx B-Series audio analyzers, designed for professional digital audio interfacing
- Provides AES3 / AES-EBU (balanced XLR), S/PDIF (BNC), and TOSLINK optical I/O for wide compatibility with consumer and professional equipment
- Enables generation and analysis of digital audio signals across multiple standard formats for device testing and validation
- Supports advanced signal impairment generation for robust testing of AES/SPDIF/TOSLINK receiver tolerance
- Integrates with APx software for automated audio measurements, diagnostics, and compliance testing workflows
- Used for evaluating DACs, ADCs, AV receivers, TVs, and other digital audio devices in R&D and production environments
- Designed to work with APx modular analyzers (e.g., APx555, APx52x series) as part of a scalable digital I/O test system

Mere information
Beskrivelse
The APx ADIO (Advanced Digital I/O) module provides AES3, AES/EBU balanced digital I/O on XLR; unbalanced SPDIF digital I/O on BNC; and TOSLINK optical digital I/O. “Advanced” in the ADIO module’s nomenclature reflects its ability to generate impairments for sophisticated test of devices via AES/SPDIF/TOSLINK, a feature that is unavailable in the DIO module.
Advanced Master Clock
The AMC module handles input and output clock signals to synchronize APx B Series analyzers with external equipment (or vice versa). This module also enables jitter generation and analysis in APx B Series analyzers with Advanced Digital (ADIO), Digital Serial (DSIO) or PDM modules installed. The AMC module is standard on B Series APx555 analyzers.
